Rolling Ridge Cottage
Even in the hot and humid of West Virginia, USA the building requires very little heating or cooling. The home's efficiency is because of the solar orientation and passive solar design. Lots of south facing windows allow low winter sun to hit a thick cob wall. The sun heats the wall in winter, providing free heat but the same wall is completely shaded in summer, so it acts like a cooling wall, absorbing excess heat & humidity from the air in the house during the humid summers. The house has a rubble trench foundation, living roof, straw bale and cordwood exterior walls, cob and light clay interior walls, adobe floors, natural clay and lime plasters, and lots of salvaged materials.
